New Cloud Security Guidance from CSA
Blog Article Published: 07/17/2024
In the last seven years, several revolutionary developments have occurred in the cloud computing industry. Considering the impact of these changes, CSA has released a new version of our Security Guidance for Critical Areas of Focus in Cloud Computing. We have completely revamped this updated 5th version to align with modern technologies and challenges.
As with previous versions, Security Guidance v5 helps you mitigate cloud risks, while simultaneously supporting business goals. You can view the Security Guidance as your actionable roadmap for adopting the cloud paradigm. We here at CSA see it as an essential resource for any IT security professional.
Key Differences from Version 4
Security Guidance v5 has undergone significant updates to align with the current state of the cloud industry. These updates include:
- Consolidated Domain Structure: The content has been more effectively grouped into 12 domains versus the 14 domains in v4.
- Refined Focus Areas: Version 5 features increased coverage on cloud workloads, application security, CI/CD, DevSecOps, and automation.
- Strengthened Core Areas: We have extended and improved the sections on GRC, auditing, IAM, and incident response.
- Added Crucial New Topics: AI and Zero Trust have replaced the content on IoT and mobile data. New domains dedicated to organizational security and security monitoring have been added. Additionally, we've added explicit references to critical topics such as resilience and data lakes.
- Reduced Coverage of Laws and Regulations: Version 5 moves away from detailed discussions about legal and regulatory specifics.
- Removed Security-as-a-Service: We now discuss cloud security tools across several domains.

Quick Reference Guide
We strongly encourage all IT professionals to read the entire document, but we understand if your time is limited. If you just want to check out the particularly new content, we recommend focusing on these domains:
- Domain 6: Security Monitoring - This domain contains a ton of new content, including discussion of security monitoring, cloud telemetry, security analytics, and data lakes.
- Domain 9: Data Security - Again, make sure to read the sections about data lakes.
- Domain 10: Application Security - Pay special attention to the CI/CD pipeline.
- Domain 11: Incident Response and Resilience - Don’t skip the section on resilience at the end!
- Domain 12: Related Technologies and Strategies - We didn't even mention Zero Trust and AI in Security Guidance v4.
Expand on the Learnings from Security Guidance v5
Reading the Security Guidance is just the first step on your journey toward secure cloud computing. We recommend taking advantage of these other CSA resources next:
